Continuous rotation of a surgical instrument

A method of providing continuous rotation to an electrosurgical device, comprising the steps of:

• providing a housing defining a first rib and a second rib and supporting a shaft of the electrosurgical device for rotation about a longitudinal axis, wherein the shaft includes a slot;
• coupling a rotor having first and second sets of pins electrically isolated from each other and positioned concentrically to the shaft of the electrosurgical device so that the first set of pins are positioned in contact with one of a concentrically positioned pair of rings of a stator that is fixed against rotation and the second set of pins are positioned in contact with the other of the pair of rings, wherein the rotor includes a tang that engages the slot of the shaft and the stator is positioned in abutting relation to the first rib such that the first rib prevents rotation of the stator;
• providing a bearing between the rotor and the second rib and in abutting relation to the rotor and the second rib so that the rotor can rotate while contact is maintained between the first set of pins and the one of the pair of rings and between the second set of pins and the other of the pair of rings;
• coupling the first and second sets of pins to an electrosurgical implement of the electrosurgical device that is mounted to the shaft;
• and
• coupling the pair of rings of the stator to an electrosurgical power source so that the electrosurgical power source is in electrical continuity with the electrosurgical implement.
